Short-distance dispersal of Hypothenemus hampei (Ferrari) females (Coleoptera: Curculionidae: Scolytidae) during the coffee tree fruiting period

Abstract: The coffee berry borer (CBB), Hypothenemus hampei (Ferrari), is a multivoltine species closely associated with coffee crops worldwide, causing severe damage to the bean. In Mexico, as in all tropical regions, CBB survives during the inter-harvest period in residual berries on the ground or in dry berries remaining on the branches, and then disperses in search of the first suitable berries. In this study, we investigated how CBB dispersed from the first infested nodes during the fruiting period of Coffea caneph… Show more

“…The cooccurrence of older, infested, berries with younger, intact, berries explains this uniform distribution of infestations. In tropical settings, where coffee trees produce a single large annual crop, colonisation tends to spread gradually, aggregatively, and to become homogeneous when infestation levels are high (Román-Ruiz et al, 2018).…”

“…Plots were 40 m apart from each other in each row, and 7 m apart between rows to reduce drifting effects and contamination between the treatments. According to Baker (1984), this distance minimizes the migration and displacement by wind or flight of adult coffee berry borers between treatments, as these insects travel short distances when food is available, according to Román-Ruiz et al (2017).…”

“…El ensayo fue conducido en base a la estructura de un diseño bloques completos al azar debido a la necesidad de controlar la pendiente del terreno, se evaluaron seis tratamientos con tres repeticiones cada uno, generando un total de 18 unidades experimentales, las cuales estuvieron separadas por una distancia de 10 m entre sí. Este distanciamiento se considera razonable para minimizar la migración y desplazamiento de los adultos de BC entre tratamientos, motivado por el viento y vuelo (Baker 1984;Dufour 2004), aunque que el insecto viaja distancias cortas en la etapa fenológica en el que se desarrolló el ensayo (Román-Ruiz et al 2017). Cada unidad experimental tuvo un área de 100 m 2 , lo que determinó un área total de 9.100 m 2 donde se realizó la ejecución física del experimento (Tabla 1).…”
